Answer:
324,632 possible combinations
Step-by-step explanation:
We are looking for the amount of combinations of 5 students we can have in a class of 35 students. We write this as 35_C_5. The formula for finding the number of combinations of x objects from a set of y objects is x_C_y =
.
Then we have:
35_C_5 = 
--- expand
--- simplify
324,632 --- simplify
324,632 possible combinations

Step-by-step explanation:
Use the formula for average rate of change over an interval of two points:

We have two points: (-2, -1) and (0, -1). Plug the values into the formula:

The average rate of change over the interval [-2,0] is
0.

Answer:
Two complex (imaginary) solutions.
Step-by-step explanation:
To determine the number/type of solutions for a quadratic, we can evaluate its discriminant.
The discriminant formula for a quadratic in standard form is:

We have:

Hence, a=3; b=7; and c=5.
Substitute the values into our formula and evaluate. Therefore:

Hence, the result is a negative value.
If:
- The discriminant is negative, there are two, complex (imaginary) roots.
- The discriminant is 0, there is exactly one real root.
- The discriminant is positive, there are two, real roots.
Since our discriminant is negative, this means that for our equation, there exists two complex (imaginary) solutions.
